This is a very provocative analysis. Are there implications for aging science? “Let’s start with calorie restriction, shall we? Everyone knows that it slows aging, isn’t it? Well, not really. Take a look at the chart below… Each bar represents […]
What a breakthrough! This builds on the researcher’s 2021 finding that linked DNA breaks with learning. “When a long-term memory forms, some brain cells experience a rush of electrical activity so strong that it snaps their DNA. Then, an inflammatory […]
“Scientists achieved this effect by changing each animal’s ‘epigenome’, one feature of which is a collection of chemical tags that are bound to DNA and affect gene activity. After the treatment, activity of the targeted gene dropped and remained low […]
Our bodies produce keratin, and it’s already added to shampoos to strengthen hair. When researchers encapsulated it in microspheres, good things happened. “In the keratin microsphere-treated group, hair regrowth commenced on the second day after treatment, with the growth rate […]
So much potential! “An alternative to genome editing can reduce the activity of a gene that affects cholesterol levels without changing the DNA sequence — and does so for an extended period, according to a study in mice.” ~ learn more
It’s hard not to get excited about the cutting edge lab results that the ability to edit DNA has unlocked. “If we give it to aged mice, they rejuvenate. If we give it to young mice, they age slower. No […]
“In their study, the team fed mice a diet that restricted the intake of cysteine and methionine, two sulfur amino acids… Not only did they find that the diet made glioblastoma cells more likely to die from ferroptosis, but they […]
The liver is regularly bombarded with foreign substances, and is home to antigen-presenting cells that train the immune system to tolerate foreign proteins rather than attacking them. Delivering carefully selected protein fragments to the liver helps put a damper on […]
Long-time readers will know that the study’s findings are not news, but its publication is a milestone. “In the Cell paper, Sinclair and his team report that not only can they age mice on an accelerated timeline, but they can […]
A lot of experiments with mice measure their running on wheels in their cages. Some had worried that the running was a symptom of captivity rather than a natural behavior, invalidating many experiments. So, between 2009 and 2013 researchers placed […]
